CST 4.5" Stage 1 Suspension System — 14-18 Chevy / GMC 1500 4WD

A true 4.5" of lift via UCA/LCA drop — for 2014–2018 Chevy Silverado / GMC Sierra 1500 (2WD & 4WD). Works on all three factory spindle/arm configurations, keeps O.E. track width, steering and 4WD CV geometry, and retains the factory load rating for towing.

What this stage includes

• Boxed, gusseted UCA drop brackets and high-clearance LCA cross-members
• Laser-cut front coilover extensions
• Boxed diff and sway-bar drop brackets
• Lower aluminum skid plate that ties the cross-members together and protects the diff
• Hand-fabricated 3" rear lift blocks, zinc U-bolts, and all hardware
• Reuses your factory coilovers via the included extensions — longer rear shocks sold separately
